Detonation chambers

The destruction of fuzes and supplemental charges has changed. Instead of using a standard detonation chamber, they are simply placed in the MPT and allowed to decompose or detonate. At the same time, the MPT design has changed—it now uses a steam-heated industrial oven with internal steam recirculation, which has not been demonstrated for destruction of fuzes and supplemental charges.

Air beg modules are generally fastened to the center of the vehicle s staring column with four bolts. A thin tin plait coven the components of the module. It must becul sway with tin snips, exposing detonator chamber and sir bug. Do not damage thewhitemfionelectrkalplugfhtmmit upper left. 

TUrn the module over on its soft plastic face and observe the back of the unit. A piece of thin tin, fastened with four rivets, will protect the gas-generating portion of the module. Cut away this tin plate, exposing the back of the module. An aluminum Big Mac-like detonating chamber will be...

After tin shield is removed, the heavy aluminum detonating chamber can be seen. Four rivets, one in each corner, secure this piece to the air bag. Grind off the rivets and separate. 

For the experimental measurement of the detonation velocity in a chemical laboratory (indoors), it is advisable to carry out the detonation experiment in a so-called detonation chamber (Fig. 7.15). Usually, the explosive is filled (pressed or...

ND particles with diameters about 4 nm have 20% of the total number of atoms on the surface. Because the physical properties of nanocrystals are strongly size-dependent, it is crucial to control and accurately measure the crystal size. To some extent, ND crystal size can be controlled by the synthesis conditions, for example, the volume of the detonation chamber [79]. However, it is not something that can be easily changed. Therefore, ND suppliers provide powders of a size that they can... 

The October 8, 2007, CDCAB resolutions on treatment of noncontaminated rocket motors repeated the board s earlier position indicating potential support for either offsite recycling at a government facility or treatment at the planned BGCAPP supercritical water oxidation (SCWO) facility. The resolutions also supported study of the use of the static detonation chamber for noncontaminated rocket motors only (CDCAB, 2007). 

Manual operations are now minimized by slipping precast donor explosives over the projectile and mechanically moving the round into the detonation chamber. The substitution of hot air purging for washing the chamber and detonation debris with decontamination solution eliminated a set of operations that probably posed a significant risk of exposure to chemical agent. 

Chemical munitions are placed in a cardboard box or carrier, which is transported to the top of the kiln. The boxed munitions are fed into the kiln through two loading chambers, each having its own door. The boxed munitions are dropped onto a heated (500°C-550°C) shrapnel (scrap) bed at the bottom of the detonation chamber. If sufficient energy from energetics in the munition is released, no additional external heating from the electrical resistance elements is required. If the munition does not contain energetics, additional heat can be provided by the electrical resistance elements. 

As tested in Belgium, the CDC consisted of three main components the detonation chamber, an expansion chamber, and an emissions control unit, the latter comprising a particle filter and a bank of activated carbon adsorption beds (NRC, 2002). The maximum explosive rating of the T-10 mobile unit is 12 pounds of TNT-equivalent, including the donor charge used to access the burster and the agent. 

The detonation chamber is connected to a larger expansion chamber. A projectile wrapped in explosive is mounted in the... 

The latest versions incorporate a mechanical system to move explosive-encased munitions from the preparation area through a reduced pressure vestibule into the detonation chamber. Double doors on the detonation chamber minimize any chance that agent vapors or detonation debris might escape. For standard varieties of munitions, the explosive charge is precast in a plastic form that can be slipped over the projectile. This packaging mode minimizes worker contact with the munitions and facilitates the mechanical transport of the projectile into the detonation chamber. Nonstandard items may require wrapping the munitions in sheet explosive, as was done in Belgium. 

Controlled detonation chamber (CDC) update. Briefing by DeMil International to the Non-Stockpile Program Core Users Group, November 2004. 

The CDC appears to be well suited for destroying a range of either chemical or conventional munitions (NRC, 2002). While it has yet to be tested for the destruction of nerve agents (cf. Table B-2), the hot, wet, oxidizing atmosphere in its detonation chamber can reasonably be expected to decompose these compounds rapidly. The CDC has also not been demonstrated for munitions encased in overpacks for storage. 

Models of the CDC up to the TC-60 are designed to be transportable although there may be some restrictions on road transport because of the physical size of the detonation chamber. These models are designed to be set up within 5 days. The typical operating crew comprises 18 staff, including laboratory, safety and supervisory personnel (DeMil International, 2005b). 

Unlike the EDS and the DAVINCH, the CDC does not have provisions for holding, testing, and retreating detonation debris before opening the detonation chamber, a feature that many public stakeholders desire. 

Kobe Steel has estimated the DRE for the detonation chamber at >99.9999 percent. However, the procedures were not consistent with U.S. regulatory requirements—that is, the methodology cannot be used to calculate the regulatory DRE. The committee believes, however, that the DAVINCH technology should be able to achieve a high DRE, considering that no agent has been detected downstream of the detonation chamber.
